DEMO PROGAMABLE FUSE & SHAPED CHARGE AMUNISI 57MM BOFORS PADA SISTA AL.
DECRIPTION OF BOFORS 155MM BONUS. Bofors 155 mm Trajectory Correctable Munition (TCM) was still in the design stage when it was at least partially melded into Excalibur, so the following information should be regarded as highly provisional and may be subject to extensive change.A projected 155 mm TCM could have four main internal sections. In the ogive, and behind a nose-mounted fuze, the internal volume will be occupied by guidance and trajectory correction timing and control electronics. The following section will contain a number of impulse motors with their vents around the projectile's centre of gravity to effect trajectory corrections. Then follows the main payload section which could vary in content from conventional high explosive or similar payloads to BONUS anti-armour submunitions, dual-purpose bomblets or naval target warheads. The base of the projectile will be occupied by a range-enhancing Base Bleed (BB) unit with four spring-out folding stabiliser fins.The original intention was that a tracking radar would follow a TCM once fired until it reached a point close to its apogee. The fire-control system would then calculate a corrective vector to ensure the projectile reached its intended target area. Vector data would then be discretely transmitted via an ECM-resistant communications link to the TCM onboard guidance system. The necessary corrections would then be introduced, firing the required impulse motors in a controlled sequence at precisely calculated times and angles. As soon as the trajectory change data had been transmitted the tracking radar would be switched off.
